[Mediawiki-l] Uploading a PDF

[city wiki]

I copy-paste from


http://meta.wikimedia.org/wiki/Uploading_files



Q: Why do I get the message: "The file you uploaded seems to be empty. This
might be due to a typo in the file name. Please check whether you really
want to upload this file."

One reason for this is that something below mediawiki such as PHP or the web
server is limiting the size of http requests. See the next question.

Q: What affects the *maximum file size* that can be uploaded?



   - Change "upload_max_filesize = <Number>M" in your php.ini file, where
   <Number> is the limit in MBytes.
   - Change "post_max_size =<Number>M" in your php.ini file as well and
   restart apache.
   - If this php4 parameter is too low, you get the error message "The
   file you uploaded seems to be empty. This might be due to a typo in the file
   name. Please check whether you really want to upload this file."
   - Apache has a directive "LimitRequestBody", which controls the
   maximum number of bytes allowed in ANY http request. If this limit is not
   somewhat larger than upload_max_filesize, the above message will appear for
   files near or above this limit. This directive may appear in various places
   in the apache configuration files, or in an .htaccess file. The effect of
   this directive may be global, or limited to a particular virtual host or
   directory, depending on where it occurs. Consulting the Apache documentation
   is advised if you run across this directive to understand how it is being
   used.

Some distributions use this directive to guard against denial of service
attacks. For example the php module configuration for Apache2 on RedHat
limits the request body size to 524288
bytes<https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=76976>.
Look at /etc/httpd/conf.d/php.conf. -- Other distributions may place the
directive in other places according to their individual configuration file
policies.

   - MediaWiki's SpecialImport.php page has a hardcoded MAX_FILE_SIZE on
   the form that you may need to increase manually.

   - PHP's memory_limit may also place a limit on the maximum file size.
   See the note below if you find that you are getting a memory exhausted error
   in the Apache error log.
